Upload camera photo with s3_direct_upload

Upload camera photo with s3_direct_upload

I have a rails app which has some pages designed to be accessed through a
mobile phone. These pages contain code to allow the user to take photos
from their phone:
<input type="file" accept="image/*" id="capture" capture="camera">
I would like to be able to upload the photos captured from the phone's
camera up to s3. I have been watching a Railscast to get an idea of how to
do this: http://railscasts.com/episodes/383-uploading-to-amazon-s3
I have implemented the uploader gem
(https://github.com/WayneHoover/s3_direct_upload) based on that railscast
and have it working on the desktop browser with selecting files. What I
would like to do is integrate it with the html5 capture="camera" code as
shown above. Take the photo with the phone and then upload it to s3.
Is anyone able to offer any help with this?
Thanks.
